Vickers E

The Vickers 6-Ton Tank, also known as the Vickers Mark E, was a light tank invented in the United Kingdom in 1928. From 1932 to 1939, Poland used the Vickers E as one of its main tanks, while Finland used it from 1938 to 1959. The Soviet Union purchased the design and developed the T-26 tank as a Russian copy, and Italy's capture of some of the Soviet tanks during the Spanish Civil War would lead to them inventing the Fiat M13/40 tank.
